Observation of structures in four pion invariant mass in sntiproton-4He annihilation at rest (Obeliz data, PS201 experiment at LEAR)
Creators
Description
Two sharp structures at about 1200 MeV/c2 and 1400 MeV/c2 are observed in the π+π-π+π- system invariant mass in antiproton-4He annihilation at rest. No similar signals are seen in the corresponding antiproton-proton data. Analogous observation has been made in stremer chamber data
